Vertical Shaft Sand Making Machine: The Core Equipment For Fine Processing Of Sand And Gravel Aggregates

Vertical shaft sand making machine (VSI) has become the key equipment in the sand making process of mining crushing industry by virtue of the crushing principle of “stone hitting stone” and high-efficiency design. Its core advantages include:  

1. excellent particle shape: the high-speed rotor will project the material to impact, and produce rounded and well-graded sand with controllable powder content (3%-15%), which meets the demand for high-standard concrete sand;  

2. Flexible and efficient: hydraulically adjust the rotor speed and feed volume, suitable for granite, basalt, tailings and other raw materials, single machine processing capacity of 60-650 tons / hour;  

3. Low carbon and energy saving: energy consumption is reduced by 30%-40% compared with traditional equipment, modular structure reduces maintenance costs, and the utilization rate of the equipment is over 90%.  

In the application, the vertical shaft sand making machine focuses on serving the sand and gravel aggregate production line fine crushing and shaping (such as processing 0-15mm gravel to 0-5mm high-quality sand), construction waste regeneration sand (waste concrete crushing and then resourcing) and other scenes. Take a limestone processing project as an example, VSI equipment will be jaw crusher, cone crusher coarse crushing products after secondary processing, mechanism of the sand yield of 95%, instead of natural sand used for ready-mixed concrete, the comprehensive income increased by 25%.  

As the demand for green mines and high-quality aggregates grows, the vertical shaft sand maker has become the core equipment for the industry to reduce costs and increase efficiency with its high yield and low emission characteristics.
